+-KakaoTechCampus Step1 2차 미니과제
+-안드로이드 프레임워크를 사용하여 모바일 앱으로 오목을 구현한다.
+
+#기능 목록
+1. 오목판 초기화
+    - 오목판을 비워져있도록 구성한다.
+2. 돌 놓기 기능
+    - 사용자는 오목판을 클릭하여 돌을 놓을 수 있다.
+    - 흑돌과 백돌이 번갈아가면서 돌을 놓도록 한다.
+3. 승리 여부 확인 기능
+    - 가로나 세로, 대각선으로 다섯 개의 연속된 돌이 있는 확인한다.
+    - 렌주 룰과 같은 복잡한 룰을 고려하지 않고, 6목 이상의 장목도 승리 조건으로 인정한다.
+4. 무승부 기능
+    - 판을 전부 돌로 채웠어도 승부가 결정나지 않으면 무승부로 처리한다.
